Your driver was fully and successfully installed by win 10 finally. I just purchased a FeelTech Function Generator that uses this driver to interface with the Generator’s set-up software. No matter what, the software does not recognize the USB port for the communication. The software is called FY2300. Any ideas ???

Hello, it doesn’t work for me, but I don’t get an USB 2.0 serial in the device manager but Unknown USB Device (Device Descriptor Request failed). I installed the driver but it didn’t help and I can’t change it manually because my windows tells me it is not a valid driver.

Hi, when you get Device Descriptor Request failed you need to restart your computer. Then unplug everything and reconnect﻿. If it still doesn’t work, there may be a power issue – try to use shorter USB cable or connect to other USB port.
